Why brown bears have smelly feet
Most mammals rely upon scent for intraspecific communication. As most bear species have large home ranges and are non-territorial, scent deposit while walking could be an effective way to communicate with conspecifics. Here, the existence of pedal glands in brown bears and their role in chemical communication are investigated from a histological, biochemical and behavioural perspective. Eccrine glands were found in footpads, and prominent apocrine and sebaceous glands in the interdigital, metacarpal and metatarsal skin sections. Pedal scent contained 26 compounds including carboxylic acids, important constituents of mammalian secretions. Six of these compounds were exclusive for males. Finally, a specific marking gait like a "dance" recorded in the field is described, mostly performed by males. This study supports the existence of chemical communication through pedal marking in brown bears and suggests sex-coding potential of pedal scent.. información[at]ebd.csic.es: Sergiel et al (2017) Histological, chemical and behavioral evidence of pedal communication in brown bears.
